3 Guys Restaurant

On any given afternoon, this Greek diner on Madison Avenue is filled with a mix of old ladies who've been coming for their daily grapefruit and cottage cheese for 30 years, overacheiving children in school uniforms eating fries, art dealers selling Picassos over salad, and people who just went to the museum. It's not the best food around, but it’s as entertaining a cross-section of the neighborhood as you can find.
